None of these seem really better than testsrc2, they introduce a new
non-intuitive name. For now, I think I will stick to testsrc2.

This would be useful indeed. Unfortunately, all the drawutils code is really
8-bits-centric. If someone updates it to work with higher bit depths, then
this source would be able to somewhat make use of it: with a little change,
the diagonal gradient and the noise checkers can make use of the low order

For high bit depth, I suspect some kind of fractal or other mathematical
pattern generator would be more suited.
